: : Where
did the term "Oxbridge" come from? I'm also wondering if there is such a thing
as an Oxbridge accent. I once introduced two Oxford graduates, whose accents mutated
as they spoke into something very unlike the way either had spoken before, clipped,
fast and rather hard-to-understand. Perhaps someone experienced in these matters
could comment.

You jogged
my memory and I realised that Virginia Woolf mentions "Oxbridge" in "A Room of
One's Own" published in 1929

"Fiction here is likely to contain more truth than
fact.Therefore I propose, making use of all the liberties and licenses of a novelist,
to tell you the story of the two days that preceeded my coming here-how, bowed
down by the weight of the subject whidh you have laid upon my shoulders, I pondered
it, and made it work in and out of my daily life. I need not say that what I am
about to describe has no existance; Oxbridge is and invention; so its Fernham;
"I" being only a convenient term for somebody who has no real being. Lies will
flow from my lips, but there may perhaps be some truth mixed up with them; it
is for you to decide whether any part of it is worth keeping."
